Referring to the drawings, a machine is shown comprising a frame having end'portions II and I2. While these portions could be made of various shapes and materials, in the embodiment of the invention illustrated each is shown as comprising a base member Ma and I2arespectively which is in the form of an angle bar and has its angle directed outwardly. Vertical'members IIb and I2?) extendupward from andare secured respectively to members I la and I2a, said members having their angles directed'outw'ardly and'having one vertical'fiange directed rearwardly. Rear members II'c and I extend upwardly and forwardly from and are secured to base members Il'a and 12a respectively, these members also having their angles directed outwardly and having one verticalflange directed forwardly. Members I'Icand' I ll) are connected at their upper portions by a horizontal member I'Id also illustrated as an angle bar having its angle directed inwardly and one flange extending inwardly. Members He and H5 are connected to member I la by the headed and nutted'bolts I3 andthe members I20 and I273 are connected to member I2a by the headed" and nutted bolts I l. Member I'Id is connected'to members Ill) and He by the headed and nutted bolts I5 and" said bolts also pass through andiassist in securing to said members gusset plates i6. Additional headed and nutted bolts IT pass through member lid and gusset plates IIi'and additional headed and nutt'ed'bolts I8 pass through the gusset plates I6 and members I lo and I Ib respectively, securing said plates to said latter members. A top member 12d extends horizontally between the upper ends of members 'I2b and- I2c, the same having its angle directedinwardly and'being secured to said members by the headed and nutted bolts I9. Bolts I9 also extend through and assist in securing in place the gusset plates 20. Said plates are also securedto member IN by the headed and nutted bolts 2| andto members IZd and I20 respectively by the headed and nutted bolts 22. End frames II and'IZ'therefOre constitute similartrapezoids. Saidend frames are connected at their upper ends by the front members or cross rails 23 and the rear members or cross rails it which extend betweenand are secured to members (2 and I221. While members 23 and 24 might be made in various shapes, in the embodiment of the invention illustrated they are shown as made of angle bars .hav'ing horizontal flanges engaging the horizontarflanges of members Nd and IZd'havclips or brackets 25 through which pass the bolts 26. The members Ho and l2c are braced and connected by the crossed bars 21 bolted thereto and connected at their central and crossing points by the bolt 28.

The members I lb and l 212 have secured thereto at their upper portions and spaced forwardly a short distance therefrom, channel bars 29 and 39 respectively, said bars having their channels 3 facing each other or inwardly of the machine and being spaced from the. front vertical web of members I lb and I22; by the spacing bushings or thimbles 3| through which pass the bolts 32 securing said channel members 'in place. The heads of bolts 32 are countersunk in the flanges of channels 29 and 39 so that the inner sidesof the channels are unobstructed. Said channel members have formed in their web portions adjacent the upper and lower ends thereof, elongated slots 29a and 39a respectively. A member 33 shown as an angle bar extends between the channel members 29 and 39 carried at its end by curved brackets 34 which are bolted by bolts 35 to guide blocks 38 having guide rollers 31 at their sides opposite said brackets which move in the channels of members 29 and 39 and are guided vertically therein. Another member 38 also shown as an angle bar extends between members 29 and 30 above member 33 and is connected at its ends to curved brackets 39 secured to the guide blocks 40 by bolts 4| which guide blocks have mounted thereon spaced rollers 42 also movable in the channels of members 29 and 30 and guided vertically thereby. Bars 33 and 38 have formed therein elongated slots 33a and 38a. extending substantially from end to. end thereof. Brackets 34 have their upper sides concave and are oppositely disposed to the brackets 39. Angle bars 33 and .38 have one flange extending horizontally forwardly and have their vertical flanges extending upwardly and downwardly in opposite directions and in the same plane. Blocks 36 have bolts 36a secured thereto extending outwardly through the lower slots 29a and 3911. which pass through the upper ends of and hold in place the links 43. The upper ends of links 43 are disposed closely adjacent the outer sides ofcha'nnel's 29 and 30 and are bent outwardly closely adjacent said ends and have their lower ends pivotally connected by the bolts 44 to a double ended lever ,45. The lower end of link 43 is curved forwardly and extends as shown in Fig. 4 aroundand beneath the shaft 46 to which both levers 45 are secured at the respective ends of the machine, said shaft being journaled in bearings 47 bolted to members Ill) and ll2b by the bolts 48. Levers 45 are rigidly secured to the shaft 46. The block 49 has a headed bolt orpin 49 projecting outwardly therefrom and extending through the upper slot 30a which passes through an aperture in the upper end of a link 59. The upper ends of links 50 are also disposed closely adjacent the outer sides of channel members 29 and 30 respectively and said links are bent outwardly just below said ends and extend downwardly at the outer sides of links 43 and have their lower ends connected by the pivot bolts 5! to the ends of the double arm levers 45 opposite the ends to which links 43 are connected. As shown in Figs. 4 and 5, the links 50 are disposed forwardly oflinks 43 and are curved rearwardly at their. lower ends. Said links also extend forwardly and downwardly from their lower ends so that the Vertical portion as shown in Figs. 4 and 5 is in front of the channel members 29 and 39. One of the double arm levers45 shown at the right hand side of Fig, 1 has a projecting hub from which extend radially and.

substantially at right angles to each other, handle arms 45a and 45b, the same having secured at their end portions the handles 52. The bar 33 has secured thereto in the corner of its channel blocks 53 preferably made of wood and one side various materials, in the embodiment of the invention illustrated it is shown as comprising spaced side pieces 56a between which extend the spaced slats 5612. Another strip 51 extends lengthwise beneath the outer side of table 56' and has secured adjacent its ends angle brackets 58. Bars 59 illustrated as angle bars are secured to the brackets 58 and have their lower ends secured to the front of base members I la and l2a respectively and by the bolts I3 and I4 respece' tively. The blocks 53 also have secured to their 7 secured adjacent its ends a pair of caster brackets 64- carrying the caster wheels .65, Caster wheels 65 run upon the members 66 illustrated as angle bars having their vertical flanges secured by bolts 61 to members No, I2c'and llb and [2b and having their horizontal flanges facing inwardly and on which rollers 65 run. A rather wide strip or board 68 extends horizontally just above and parallel to members 66'and is also secured by screws 69 to theend frame members I2c and I212. The member 68 extends from members [2b rearwardly of the machine and has its rear edge alined with the rear end of member 66. Another plate'or board 68a is provided, '50

similar to board 68, and of the same length. Board 680. is carried by and has "secured thereto a pair of parallel rods 68b which rods are joined at their ends bya cross piece 680 having formed therein a grip handle 68d. Rods 6812 are guided in bores drilled in a plate 68c having bosses 68 projecting outwardly therefrom. Rods 6822 are slidable through said bores so that board or plate 68a can be moved todifferent positions as indicated in dotted lines in Figs. 1 and 6, always remaining at right angles to strip 63 and thus.

be disposed at different distances from the end of the machine. therein a series of holes 689 adapted to be en-'- gaged by the downwardly turned ends 68h of resilient or spring arms68z secured to? the cross member 68c, said projections 58h extending downwardly through the bosses 68f. With the described construction, plate 68a. can be moved lengthwise of the machine in parallel relation to' plate 68 and can be held in anyone of several positions 'by means of spring arms 681'.

A carriage I9 is provided, movable longitudinallyofthe frame of the machine on members 23 and 24, which carriage is shown as comprising side members 190. illustrated as made from 6 Bars 6811 each have formed angle bars having one flange horizontal and their angles directed away from each other, the vertical flanges extending downwardly from the horizontal flanges. Bars 10a are connected by the cross bars 10b and are further connected at their central portions by a bar 'II illustrated as in the form of a T-bar with its central web extending vertically. A bar 12 of flat form reotangular in cross section extends vertically from the front of said carriage, the same being secured to the front member 10a and to member 'II. Bar I2 has securedto its front side a bracket I3 having forwardly extending lugs 130. at its top and bottom apertured to form guides for a vertically movable plunger I4 shown as cylindrical in form. Plunger I4 has a block I5 secured thereto, the sides of which are embraced by downwardly extending arms disposed at either side of a yoke bracket 18 embracing plunger 14 and bracket I3 and having projecting outwardly therefrom a handle 16a. Yoke bracket 18 has projecting rearwardly from its yoke or open portion an arm 16b. Arm 16b has'pivoted at either side thereof by a pivot bolt 18a, the upper ends of a pair of links I8, the lower ends of which are disposed at either side of the web of bar 'II and pivoted thereto by the pivot bolt 19. The bar I2 has at its upper end a pair of rearwardly and horizontally projecting spaced arms 12a and the upper ends of a pair of springs 11 are connected respectively to these arms, the lower ends of said springs being connected to arms 16b just rearwardly of the yoke portion of the bracket I6. The plunger I4 has secured to its lower end a block or holder 80 to which is removably secured a needle 8|, said needle being held in place by a screw 82 and being removable by loosening said screw. Needle 8| is sharpened at its lower end and has formed in one side an open ended slot or eye 8Ia which extends at an angle to the axis of said needle. The angle members 10d have secured therein adjacent each end thereof studs 83 on the lower ends of which are journaled rollers 84 disposed to engage the inner sides of the vertical flanges of angle bars 23 and 24. Said angle bars 10a also have secured in their vertical flanges a short distance from studs 83, the studs 85 on which are journaled rollers 86 disposed to engage the top of the horizontal flanges of angle bars 23 and 24. The angle bars 10a also have secured at the outer sides of the angles and to the vertical flanges depending brackets 81. Brackets 81 have horizontally disposed studs 88 therein on which are journaled rollers 89 disposed to engage the bottoms of the horizontal flanges of angle bars 23 and 24. From the description it will be seen that the carriage comprising the angle bars 100; is thus supported by the rollers 86 on the angle bars 23 and 24 and is guided in a rectilinear path by rollers 84 and is prevented from moving vertically by the rollers 89. The carriage thus rolls easily along the members 23 and 24. I

The carriage I0 has secured thereto in the rear of bar I2 a hollow casing I02 bored to receive a verticaly movable plunger I03 having a pin I04 secured therein and projectingat one side thereof, which extends through a slot mm in the side of casing I02. A compression coil spring I05 is disposed in casing I02 engaging the top of plunger I03 at one end and engaging at its upper end the plug I06 threaded into the top of casing I02 and having an angularly shaped projecting portion adapted to, be engaged by a wrench. Plunger I03 is forked at'its lower end and has secured therein a pin I01 on which is journaled a small roller I08. The roller I08 is adapted to engage in any one of a plurality of semi-cylindrical notches I08a formed in a bar I09 which is substantially square in cross section. The notches I09a are disposed midway between the sides of the bar and there is a series of such notches on each side of said bar. Bar I09 extends through an opening in the upper portion of the T-shaped member 'II and extends from end to end of the machine above member 23, the same having adjacent its ends reduced portions journaled in brackets IIO mounted on the end members at and I2d. At the left hand end of the machine as seen in Fig. 1 bar I09 has secured thereto a disc III having on its outer face and spaced 90 degrees apart, the numbers 5, 6, 7 and 8. Disc III is provided with notches IIIa also spaced 90 degrees apart, any one of which is adapted to be engaged by the projection I I2a extending from a spring lever II2 secured to one of the brackets I I0. Shaft I09 can therefore be rotated by means of the disc III and maintained with any one of its sides uppermost and adapted to be engaged by the roller I08.

As'shown in Figs. '7 and 8, the plunger I4 may have secured thereto a head 80 having secured therein a pair of needles 9| and 92 removably held in said head by the screws 93. Needle 9| has an open ended slot or eye 9m adjacent its lower pointed end, said slot extending downwardly into said needle at an angle to the axis thereof. Needle 92 has an open ended slot or eye 92a adjacent its lower pointed end and this slot extends upwardly in said needle toward its bottom at an angle to the axis of said needle.

In Fig. 9 a gauge member or dolly 84 is shown, over which the tape is tied in the tape-tying operation. In Figs. 10 and 11 another type of gauge or dolly is shown, which comprises a substantially elliptical or oblong member II4 which is provided with an opening at its lower end so that member I I4 can be placed on the vertical flange of member 38 as shown in Figs. 10 and 11. An arm II la extends forwardly from the oblong portion of member H4 and the member II ib projects some distance at either side of arm I I la, the same being oblong in vertical cross section. Member I Mb extends parallel to the vertical flange of member 38.

In operation when a mattress; designated IOI, is to be tufted, the same is placed upon the table 62 and at this time the members 33 and 38 are separated and in a position shown in Figs. 1 and 4 and. plunger I4 is elevated as shown in Figs. 1 and 4. One side of the mattress is supported over the bar 33 and extends between bars 33 and 38 onto the narrower work table 56. The line in which the tuftings or tufts are to be formed is disposed between the bars 33 and 38 and in alinement with the line connecting the centers of openings 33a and 38a. The number of tufts invarious mattresses vary, in some there are five tufts spaced lengthwise of the mattress, in others six, and in others there may be seven or eight. The operator first positions board or plate 68a in the desired position to give the number of tufts desired. In positioning plate 680, the operator first lifts spring arms 682' sothat their downturned ends 88h are removed from the holes 689 thus releasing rods 68b for sliding movement. The operator now grasps the handle 68d and pushes inwardly or pulls outwardly thereon as desired to move plate 68a to the desired position. 'When said plate is properly adjusted the ends 88h of the spring arms 682' will again move downwardly into a pair of the holes 68gj and rods 68b will again be locked in position with plate 68a in the desired position. The operator now moves'the end of the mattress against the plate 68a and the mattress is in position for the placing of the first tuft. It willbe understood that the operator will turn the wheel or disc Hlby moving out member H2 so that the bar I09 has its proper side turned upward. If there are to be five tufts spaced lengthwise of the mattress, the numeral 5 will be placed upward at the top of the disc and if other spacing is desired, the other numbers will be accordingly brought to the top. The mattress being thus positioned, the operator takes hold of'one of the'handles 52 and moves the same in a clockwise direction as shown in Fig. 5. This rotates shaft 46 and the double ended levers 45 and the rotation or oscillation of the levers 45 moves links 43 upwardly and moves or pulls links 59 downwardly. The operator can use both handles 52 if convenient and the lovers 45 are brought to the position shown in Fig. 5 so that the pivots 5! are moved to the right of the vertical center line throughthe axis of shaft 46 and pivots 44 are moved to the left of the vertical center line through a shaft 46. These pivots are thus past dead center and the links 43 and 50 as well as bars 33 and- 38 are locked in position. The said movement of links 43 and 50 causes the bars 33 and 38 to move toward each other and compresses the mattress therebetween as indicated by the dotted lines in Fig. 5. The mattress is thus compressed to compact and small thickness between the horizontal flanges of bars 33 and 3B and it is held in this position owing to the locking action ofthe links 43 and 50. The operator now takes hold of the lever 16a and moves the carriage longitudinally of the machine to one end of the mattress, the needle 8| moving longitudinally over member 38 and in the line of the centers of the openings 33a and 38a. The carriage is moved until roller I93 engages in end notch I091; and the carriage is then in position for the first tuft to be made. The position of member 68a will determine the position of the first tuft. This first tuft will be at thesame distance from the end of the mattress as the first notch 19a. is from member 58a. The operator now pulls downwardly on handle 16a and needle 8| pierces the mattress and passes therethrough and through the opening 33a and 38a as shown in Fig. 2. The operator now takes a tufting cord 95 which is looped as shown in Fig. 2 and has secured to one end of the loop a button or head member 96. The operator places the end of the loop in the eye 8 la and then allows lever 16 to move upwardly under the tension of springs T! which were distended when handle 16a was moved downwardly. Needle 8| is retracted and moves upwardly through and out of the mattress to the position shown in Fig. 3. As the needle 8| moves up through the mattress it pulls with it the cord 95. The operator now takes a button 91 having a staple. 98 thereon, passes the end of the loop through the staple 98 and moves the end over the button 91. The button is now held on the cord or loop 95. When this operation is completed, the operator moves to the next opening 38a in which it is desired to placethe tuft and the operation is repeated. The carriage H1 rolls freely on members 23 and 24 and the operator merely holds the handle 16a. in moving the carriage and plunger to the next position to bring the needle to the next position. 'As the carriage is moved, the roller7l08 rolls along the top a very short time.

of the bar l09-and when a slot or pocket I99a is reached, roller I08 snaps into this slot. The roller,v of course, was in one of the slots for the first tuft made and it will successively engage Y the slots as the carriage ismoved. It maybe stated that it is the common practice to take tion shown in Fig. 4. When this is done, the. bars 33 and 38 are moved apart and the mattress.

resumes its natural thickness and the cord 95 is stretched between the members 96 and 9'! and the tufts are completed. The cords 95 are of uniform length and the tufts 'will therefore all be uniform throughout the row.' It will be noted that in this position the pivots 5! are at the left of the vertical line passing through the axis of shaft 46 and the pivots 44 are to the right.

Bar 38 is thus held in its upper position as the pivot bolt 36a is at the bottom of the lower slot 39a. The mattress is now moved forwardly to bring it to the position where another row of V tufts will be made and the operator again rotates the lever arms 45a and 45b by the handles 52 to again compress the mattress. The rows of tufts are thus made successively, the mattress being moved for each row. The mattress can be reversed after half of the rows are placed therein, so that the main part of the mattress is for the greater part of the time on the wider table 62. The tufting of the mattress is thus completed'in One form of tufting known as tape-tying, is illustrated in Figs. 7 to 9. With the present machine this is accomplished'by the use of a double 7 When the needle as illustrated in'said figures. mattress has been compressed between the members 33 and. 38, the operator takes the piece of tape I09 which has been cut to the proper length 7 and places it in theeye 92a of the needle 92 having a short length of the tape projecting at one side of the needle. He then pulls down on the lever 16a moving both needles through the mattress and the tape is drawn downwardly and through the mattress by needle 92. .Both needles are now projecting below the mattress and the operator takes hold of the end of the tape I99 removing the same from the slot 92a'and moving it around the other needle 9| and into the "eye 9Ia. This can be done very quickly and the tape then occupies the position in needle 9| shown in Fig. 8. The'operator new releases lever 16a, the needles are moved upwardly through ties the desired knot Iflfla in the tape at the top.

of member 94, the knot being drawn up so that the tape is fairly taut over member 94. The

operator then moves the carriage to the next position and repeats the operation. When the row of tufts has been made. members 33 and 38 are moved apart as above described and the mattress resumes its normal width. The tufts are made by the tape I extending through the mattress and all of the tufts will be uniform due to the fact that a uniform length has been made between the bight of the tape and the knot therein, as above described. The slots in needles 9| and 92 are made to converge toward their ends so as to be substantially wedge shaped. With this construction, the tape wedges in the slot and is conveyed through the mattress without slipping in the needle.

When the gauge member I I4 is used, it is merely placed on the member 38 and can be slid along on this member as it is needed. The tape can be tied over the member ll4b at either side of the,

arm 4a. Said gauge member slips easily from the tape.

It will be noted that the member 33 has vertical movement in the guide members 29 and 30 and there is thus some movement of the outer end of the table 62. In this movement the roller 65 merely runs on the bar 66. There is likewise some pivotal movement of the table 56 and this is accommodated by movement of the bars '59 which are pivoted at their upper and lower ends.

From the above description it is seen that applicant has provided a'very simple, easily oper ated and efiicient machine for tufting mattresses. The operator soon becomes quite skillful in placing the cord members 95 in position and placing the buttons thereon, as well as in manipulating the tape H10 in the tape-tufting operation. The mattress is conveniently supported and the carriage 10 is quite easily moved to bring the needles into the desired position. The tufting operation can be completed in a small part of the time necessary to perform the same by hand. The tufting is thus very quickly done and the tufts are all uniform. It is impossible to get all the tufts uniform when the tape tufting is done by hand. At the same time the machine comprises no complicated or expensive mechanism. The machine has been amply demonstrated in actual practice and foundto be very successful and eflicient.

It will, of course, be understood that various changes may be made in the steps and sequence of steps of the method without departing from the scope of applicants invention, which, generally stated, consists in a method capable of carrying out the objects above set forth, such as disclosed and defined in the appended claims.
